p16INK4 expression is of prognostic and predictive value in oropharyngeal cancers independent of human papillomavirus status: a Hungarian study.
Head and neck cancer treatment protocols still lack well-established biomarkers of prognostic and predictive value. It is well known that human papillomavirus (HPV)-related and non-HPV-related oropharyngeal cancers are distinct entities concerning tumor biology and clinical outcome. However, there is an ongoing debate whether tumor suppressor p16INK4 status alone or both p16INK4 and HPV detection should be used in clinical settings. ⋯ Improved response rates to neoadjuvant chemotherapy were observed both in p16INK4-immunolabelled and p16INK4- immunolabelled/HPV DNA- containing groups (Fisher's exact test: p = 0.025 and p = 0.009). In conclusion, p16INK4 immunohistochemistry proved to be a reliable and affordable tool for prognostic and predictive testing of head and neck squamous cell cancers. The p16INK4 immunopositivity status alone was confirmed to be an equally precise indicator of clinical outcome as p16INK4/HPV DNA PCR double testing.

ReviewExercise induced laryngeal obstruction: a review of diagnosis and management.
Exercise induced laryngeal obstruction (EILO) is a condition where inappropriate vocal cord or glottic closure occurs during exercise. This review of the literature provides an overview of the current understanding of the definition, epidemiology, diagnosis and management of EILO. Using The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines the Cochrane, Embase, Ovid MEDLINE and PubMed databases were searched. ⋯ EILO has a high occurrence in adolescents and athletes. The CLE test is the current gold standard for EILO diagnostics. Management of EILO includes both surgical and non-surgical interventions.

Clinical value of antistreptolysin O levels in adult patients with tonsillitis: report I.
To assess the clinical value of antistreptolysin O (ASO) level in adult patients with acute tonsillitis of group A beta-hemolytic streptococcus (GABHS) etiology and its interaction with the Centor score and throat cultures data. ASO antibody titers and throat cultures were obtained from 260 adult patients with acute tonsillitis of GABHS etiology initially proven by the Centor score. The results were compared with the group of 100 adult patients with recurrent tonsillitis who underwent tonsillectomy and with the group of 100 healthy adults. ⋯ The detection of the elevated titers may lead to early antibiotherapy to tonsillitis. The Centor score is supported by the ASO data and less supported by throat cultures data. Further research should reveal if these titers might have predictive value for possible further recurrence or serve as an indicator for tonsillectomy in cases of recurrent tonsillitis.
